+       * soft-fp/soft-fp.h (FP_INIT_EXCEPTIONS): New macro.
+       * soft-fp/extenddftf2.c (__extenddftf2): Use FP_INIT_EXCEPTIONS
+       instead of FP_INIT_ROUNDMODE.
+       * soft-fp/extendsfdf2.c (__extendsfdf2): Likewise.
+       * soft-fp/extendsftf2.c (__extendsftf2): Likewise.

        [BZ #16034]
        * soft-fp/op-common.h (_FP_NEG): Document input as raw.  Do not
        copy class of input value.
